2% sodium 2C4-diethylaniline sulfonate, the preparation method is as follows:
First take an appropriate amount of aniline, mix it with sulfuric acid, and slowly heat it to make the two fully react to form aniline sulfate. This process needs to be carefully controlled temperature, do not make the temperature too high, so as not to cause side reactions.
Then, add an appropriate amount of 2-ethylhexanol to the reaction system, continue to stir, and maintain a specific temperature to make it sulfonate. This reaction is very critical, and the control of reaction temperature and time has a great impact on the purity and yield of the product.
After the sulfonation reaction is completed, the reaction solution is cooled, and then an appropriate amount of sodium hydroxide solution is added to adjust its pH value to make it neutral or slightly alkaline. This step aims to convert the sulfonic acid into the corresponding sodium salt.
Then the reaction mixture is separated and purified, often by extraction and crystallization. During extraction, a suitable organic solvent is selected, and the target product is extracted from the mixture. After distillation, the organic solvent is removed. The crystallization method can be used to adjust the temperature, solvent ratio and other conditions to make the product crystallize and precipitate from the solution. After filtration, washing, drying and other processes, pure 2% 2C4-diethylaniline sulfonate can be obtained.
In this preparation method, each step requires fine operation, strict temperature control, time control and control of the proportion of each reactant, in order to obtain high-quality products.

When storing and transporting 2% 2C4-diethylaniline sulfate aqueous solution, many precautions need to be carefully observed.
First, storage, this solution is corrosive, so the selected storage container must be corrosion-resistant, such as special glass or specific plastic containers. And it needs to be stored in a cool, dry and well-ventilated place, and must not be close to fire and heat sources to prevent temperature rise from changing its properties or even causing danger. It should also be separated from oxidizing agents, acids, alkalis and other chemicals to avoid chemical reactions caused by improper mixing. The storage place should also be equipped with corresponding leakage emergency treatment equipment and suitable containment materials for emergencies.
As for transportation, transportation personnel must undergo professional training and be familiar with the characteristics of this solution and emergency response methods. Transportation vehicles must ensure that they are in good condition and have the necessary sun protection, rain protection and leak prevention facilities. During driving, drive steadily and slowly to avoid sudden braking and severe bumps to prevent solution leakage due to damage to containers. If you pass through densely populated areas during transportation, you need to plan your route in advance to avoid peak hours and places where people gather. In the event of a leak, emergency measures should be taken immediately to evacuate the surrounding people, isolate the leaking area, and quickly report to relevant departments to handle it properly according to professional guidance. Therefore, when storing and transporting 2% 2C4-diethylaniline sulfate aqueous solution, the above precautions should be carefully followed to ensure the safety of the process.
